Answer:
Grendel's mother and the Anglo-Saxons believe in the philosophy of taking "an eye for an eye."
Just like any other mother, Grendel's mother would do anything to protect her son.
The Anglo-Saxons understood that "sacrifice" would be a part of" victory."
Step-by-step explanation:
Grendel's mother is described as an avenger, who wants to take revenge for the death of her son, with the death of the one who killed her son, even if it meant sacrificing her life. This shows that Grendel's mother, although a showy creature was an Anglo-Saxon mother and culture, a mother sacrifices herself for her son, as sacrifice is a victory in this culture and shows a strong commitment and courage.
Furthermore, revenge is based on the "eye for an eye and tooth for a tooth" philosophy showing that if you killed someone, you must die too.
